Before operating the unit, please read this manual thoroughly and
retain it for future reference.

To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
To reduce the risk of electrical shock, do not open the cabinet.
Refer servicing to qualified personnel only.
To reduce the risk of fire, do not cover the ventilation of the
apparatus with newspapers, tablecloths, curtains, etc. And do not
place lighted candles on the apparatus.
To reduce the risk of fire or electric shock, do not place objects
filled with liquids, such as vases, on the apparatus.

Do not install the appliance in a confined space, such as a
bookcase or built-in cabinet.

You are cautioned that any changes or modification not expressly
approved in this manual could void your authority to operate this
equipment.

• Before operating the system, be sure that the operating voltage

of the system is identical with that of your local power supply.

U.S.A.

120 V AC, 60 Hz

Other countries

100 – 240 V AC, 50/60 Hz

• Use only the supplied AC power adaptor .
• After operating the system with the AC power adaptor,

disconnect the AC power adaptor from the wall outlet if the
system is not to be used for an extended period of time. The
POWER switch does not turn the AC power adaptor off.

• Do not set the speakers in an inclined position.
• Do not leave the system in a location near heat sources, or in a

place subject to direct sunlight, excessive dust, moisture, rain or
mechanical shock.

Do not use alcohol, benzine, or thinner to clean the cabinet.

• Do not open the cabinet. Refer servicing to qualified personnel

only.

• Should any solid object or liquid fall into the system, have the

system checked by qualified personnel before operating it any
further.

• Although this system is magnetically shielded, do not leave

recorded tapes, watches, personal credit cards, or floppy disks
with magnetic coding in front of the system for an extended
period of time.

Although this system is magnetically shielded, there may be cases
that the picture on some TV sets/personal computer sets may
become magnetically distorted. In such a case, turn off the power
of the TV set/personal computer set once, and after 15 to 30
minutes turn it on again. For the personal computer set, take the
appropriate measures such as data storage before turning it off.
When there seems to be no improvement, locate the system
further away from the TV set/personal computer set. Furthermore,
be sure not to place objects in which magnets are attached or used
near the TV set/personal computer set, such as audio racks, TV
stands, toys etc. These may cause magnetic distortion to the
picture due to their interaction with the system.

If you have any questions or problems concerning your speaker
system, please consult your nearest Sony dealer.

The tray of this system uses soft material. You can install a
portable player connected to INPUT 1 on the tray. The cord
length can be adjusted manually (~ approx.30 cm). (See fig.
C.) Note that the Auto Power function may not work
correctly if equipment that generates microwaves, such as a
mobile phone, is installed on the tray.

When using your portable player on the
stand (see fig. D)

Attach the supplied stand as shown in the illustration. This is
useful, for example, when watching a portable video player.
You can adjust the level of the stand by changing the position of
the stand cover.

Notes
• Because light, such as direct sunlight, is refracted when it

passes through the stand, and may focus in one place (as it
would by a lens), it may cause a fire to occur at the focused
point. Please keep the stand in a place not subject to a source of
light when unattended.

• If you operate a portable player with the player installed on the

stand, this unit may fall backwards. Be sure to operate the
portable player by holding it on your hand.

• Some portable players may not be installable on the supplied

stand due to their shape.

When installing your portable audio player
on the stand while the cable supplied with
the player is connected (see fig. E)

The supplied stand has a hole for connecting a cable. Attach the
stand cover in the upper position to install the portable audio
player on the stand with a cable connected to the player. The
connected cable can be tidily routed along the groove.

First, turn down the volume on this unit. When connecting the
speakers to the headphone output, turn down the volume of the
connected device.

turn the VOLUME control on this unit. 

(See fig. G. )

The power indicator goes off.

Notes
• If connecting the speaker to a device with a built-in radio or

tuner, radio broadcasting cannot be received or sensitivity may
be reduced significantly.

• If the source device has a bass boost function or equalizer

function, set them to off. If these functions are on, sound may
be distorted.

• If the source device’s headphone output has a line switch, better

sound will be heard if it is set to on. See the operating
instructions of the source device.

• If both the device connected to INPUT 1 and the device

connected to INPUT 2 are played at the same time, both sounds
can be heard.

You can set the system to turn on automatically when an audio
signal is input from a source device. When the system is turned
on, the power indicator lights up.
If no signal is input for about 90 seconds or more*, the system
turns off automatically and the power indicator goes off.
* Automatic-off time may vary according to how the speaker is used.

Set the POWER switch to AUTO. (See fig.
F-2.)

Notes
• If the input signal level is too low, the system will not turn on

automatically.

• If a device that generates microwaves, such as a mobile phone,

is nearby, the system may be turned on unintentionally by the
device.

• If a mobile phone is connected to the system, the system may

be turned on unintentionally by noise or an incoming call.
When connecting a mobile phone, turn on/off the system
manually by the POWER switch.

• The system may not turn off automatically because of received

noise, depending on the source device.

• If no device is connected to INPUT 1, the system may not turn

off automatically, or it may turn on unintentionally.

• The beginning of the input signal may not be heard, depending

on the input signal level.

• When leaving the system unattended, set the POWER switch to

OFF to prevent malfunction.
